AMD Instinct MI300 vs AMD Radeon RX 9060 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Instinct MI300 and the AMD Radeon RX 9060. The Instinct MI300 has no recorded benchmark scores, no average score, and no nearest rivals listed. The Radeon RX 9060, by contrast, has ten recorded benchmark results across multiple test suites, an average benchmark score of 16,014, and a percentile ranking of 59 among all GPUs.

The absence of measured data for the MI300 is itself informative. The Instinct MI300 carries an average benchmark score of 0 and a percentile ranking of 50, which places it in the middle of the database distribution by default rather than by demonstrated performance. The RX 9060, with its recorded scores, achieves a percentile ranking of 59, meaning it outperforms roughly 59 percent of all GPUs in the database based on actual measurements.

Looking at the RX 9060's individual results, its strongest showing comes in Geekbench OpenCL with a score of 88,183. Its Vulkan result is 39,476, which is less than half of the OpenCL figure, indicating the architecture responds differently to those two compute interfaces. In Passmark tests, the RX 9060 scores 17,631 in G3D, 9,919 in GPU compute, 1,002 in G2D, 280 in DirectX 9, 182 in DirectX 11, 104 in DirectX 10, and 44 in DirectX 12. The 3DMark Steel Nomad DX12 result is 3,322.

The MI300's theoretical specifications suggest far higher compute potential than the RX 9060, but the database shows zero measured results for it. The MI300 lists 47.87 TFLOPS FP32 and 47.87 TFLOPS FP16 (1:1), while the RX 9060 lists 21.43 TFLOPS FP32 and 21.43 TFLOPS FP16 (1:1). On paper, the MI300 delivers 2.23 times the FP32 throughput of the RX 9060. The texture rate tells a similar story: the MI300 reaches 1,496.0 GTexel/s versus 334.9 GTexel/s for the RX 9060, a 4.47 times advantage. The pixel rate goes the other direction: the MI300 lists 0 MPixel/s because it has 0 ROPs, while the RX 9060 achieves 191.4 GPixel/s from 64 ROPs.

Memory bandwidth is where the MI300 dominates decisively. The MI300 has 5.32 TB/s of HBM3 bandwidth across an 8192-bit bus, while the RX 9060 has 288.0 GB/s of GDDR6 bandwidth across a 128-bit bus. That is an 18.5 times difference in raw memory bandwidth. The MI300 carries 128 GB of memory to the RX 9060's 8 GB, a 16 times capacity difference.

For the RX 9060, its nearest rival in the database is the NVIDIA GeForce RTX 3060 Ti with an average score of 16,129, a delta of -0.7 percent relative to the RX 9060. That means the RX 9060 trails the RTX 3060 Ti by 0.7 percent, a negligible margin. The AMD Radeon R9 370X scores 15,862, which is 1 percent below the RX 9060. The AMD Radeon RX 7700 scores 15,852, also 1 percent below. The AMD Radeon Pro W5500 scores 15,679, which is 2.1 percent below the RX 9060. These deltas show the RX 9060 sits in a tightly packed performance cluster around the 15,700 to 16,150 average score range.

The Verdict

The data presents an unusual comparison because one side has no measured results. The Instinct MI300 is a compute accelerator with no display outputs, no DirectX, OpenGL, or Vulkan API support, and no benchmark scores in the database. The Radeon RX 9060 is a consumer graphics card with full API support, ten recorded benchmark scores, and a percentile ranking of 59.

For users who need a graphics card for rendering, display output, or DirectX-based workloads, the RX 9060 is the only option with data supporting its capabilities. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and it provides 1x HDMI 2.1b and 2x DisplayPort 2.1a outputs. The MI300 lists "No outputs" and "N/A" for all three graphics APIs, so it cannot function as a display adapter.

For users who need massive memory capacity and bandwidth for compute workloads, the MI300's specifications indicate it was built for that purpose. Its 128 GB of HBM3 memory with 5.32 TB/s bandwidth, 153,000 million transistors, and 1017 mm² die size point to a server or datacenter part designed for large-scale computation. The RX 9060's 8 GB of GDDR6 with 288.0 GB/s bandwidth is a consumer-class memory configuration.

The RX 9060's nearest rival data shows it performs within 2.1 percent of four other GPUs, which indicates it is a mid-range performer relative to the database population. Its average score of 16,014 and its 59th percentile rank confirm this positioning. The MI300, with no scores, cannot be positioned relative to any of these rivals.

A user selecting between these two parts would be choosing between a compute accelerator with no measured benchmark data and a consumer graphics card with documented performance. The MI300's power requirements are substantially higher: 600 W TDP with a suggested PSU of 1000 W and 2x 8-pin connectors, versus 132 W TDP with a suggested PSU of 300 W and 1x 8-pin connector. The MI300 also uses a 5 nm process node while the RX 9060 uses a 4 nm node, both from TSMC.

Architecture Differences

The MI300 uses the CDNA 3.0 architecture on a chip called Aqua Vanjaram, while the RX 9060 uses the RDNA 4.0 architecture on a chip called Navi 44. These are fundamentally different design families: CDNA targets compute acceleration, RDNA targets graphics rendering.

The MI300 is built on a 5 nm process at TSMC with 153,000 million transistors on a 1017 mm² die, giving a transistor density of 150.4 million per mm². The RX 9060 is built on a 4 nm process at TSMC with 29,700 million transistors on a 199 mm² die, giving a transistor density of 149.2 million per mm². The MI300 has 5.15 times more transistors and a 5.11 times larger die, but the transistor density is nearly identical between the two, differing by only 1.2 million per mm².

The MI300 has 14,080 shading units, 880 texture mapping units, and 0 ROPs. It has no ray tracing cores listed and no tensor cores listed.
